What Is a Detached Garage?

A detached garage is a garage that stands on its own. It is not connected to your house. It sits on its own slab, with its own walls and roof.

That gives you a lot of freedom. You can place it where it works best on your lot. You can make it as simple or as finished as you like. And you add space without tearing into your home.

A Detached Garage Sized to Your Lot and Your Needs

We do not use stock plans. Every detached garage we build is custom.

Some owners want a two-car garage for parking. Some want three or four bays. Others want a garage with a deep side for a workbench, or a tall bay for a boat or trailer. We plan the size, the doors and the layout around how you will use it.

Your land shapes the plan too. Setbacks, slope, driveway access and utilities all matter. We look at your lot first, then size the garage to fit it and the local rules.

More Than Parking

A detached garage can be much more than a place for cars. Our clients use theirs as:

  • A workshop for wood, metal or car projects
  • Storage for a boat, trailer, ATVs or yard gear
  • A home gym
  • A quiet home office
  • Extra bays for a growing family’s vehicles

Add Power, Heat, Plumbing and a Loft

You choose how finished your garage is. We can add:

  • Electrical: Lights, outlets and power for tools or a car charger.
  • Insulation: Keeps the space more comfortable and cuts noise.
  • Heat: So you can use it through Idaho winters.
  • Plumbing: A utility sink or a full bathroom.
  • A loft: Storage or bonus space overhead.

These add-ons turn a plain garage into a space you can use every day.

Pick the Right Spot on Your Lot

Where the garage sits matters as much as how big it is. Before we plan the size, we walk your property with you.

We look at a few things:

  • Driveway access. Can you pull in easily, and is there room to turn around?
  • Distance from the house. Close enough to be handy, far enough to meet setback rules.
  • Setbacks and lot lines. Your city or county sets how close the garage can be to your property lines.
  • Utilities. Power, and water if you want a sink or bathroom, have to reach the building. A shorter run can save money.
  • Drainage. We grade the site so water flows away from the slab, not toward it.

If you’re in an HOA, the spot and the look of the garage may need their approval too. We’ll help you sort that out before we build.

Stick-Framed to Match Your Home

We build every detached garage with stick framing on a concrete slab. We do not build pole barns, steel buildings or prefab kits.

Stick framing is easy to insulate and finish. It takes the same siding, trim and roofing as your house. So your new garage looks like it belongs on the property.

What's Included in a Detached Garage Build

We run the whole job, so you only deal with one team:

  1. Site visit and plan
  2. Site work and grading
  3. Concrete slab
  4. Stick framing and roof
  5. Garage doors, windows and entry door
  6. Electrical, plumbing, insulation and heat (your choice)
  7. Permits and inspections
  8. Final walk-through

We Handle the Permits

A detached garage is an accessory building. Most cities and counties need a permit for one. The rules cover size, height and how close it can sit to your property lines.

We pull all the permits and work with the inspectors. For example, the Ada County Building Division asks for accessory structures to be included with home permit plans. Each city and county has its own process, and we handle it for you. If you have an HOA, we help you with their rules too.

First time doing any kind of construction and an ADU above our garage was quite the experience! Alex was good at letting us know each step of the way. We had a hiccup with cabinets....but even with that delay, project was done within a week of when he said it would b done! I've been told, in the construction world, that's miracle! He worked with us to keep us within our budget....even assisting on some areas so it would b amazing! I loved that he didn't "nickle & dime" us to death!! Anything extra needed was carefully shared & explained. The finished product is so much more than we could have hoped for & admired by all who view it! Thank you Alex & CEB!!

We recently had the pleasure of working with Alex from Comfort Expert Builders, who completed a ~1400SQ FT addition above our garage. From start to finish, Alex was great to work with. He was professional, approachable, and always ready to address any questions or concerns. His team moved quickly and completed our project in an impressive 3-months! Throughout the project, Alex maintained excellent communication, keeping us informed of progress and any potential issues. The construction estimate was accurate, and there were no unexpected costs or surprises. His level of honesty and reliability is rare and highly appreciated. Overall, I would highly recommend Comfort Expert Builders for any home construction projects.

Detached Garage FAQs

How much does a detached garage cost?

The cost depends on the size, site work and what you add inside. A plain two-car garage costs less than a heated shop with a bathroom. We give you a clear estimate after we see your lot.

Can you build a two-car detached garage?

Yes. We build two-car garages and larger ones with three, four or more bays.

Can a detached garage have electricity?

Yes. We can add lights, outlets and power for tools or a car charger.

Yes. Once the garage has power, you can extend your home wifi to it. Tell us early if you want a wired network line, so we can plan for it.

Should I insulate my detached garage?
